The usual automated response from HR "we cannot give advice on pensions" - which i understand. However, we had a brief last year from a very presentable Sqn Ldr from the Pay Team @ MOD Main.
She said that there WILL be pension information with actual figures provided, but obvs dependent on the actual outcome of the Pension Review.
Also, I am sure the FPS will be providing their analysis once known, but for individual cases i would suggest joining the FPS - £40 a year for for advice that may cost you 10's of thousands later down the line? Well worth it imo
